问题:
为什么提前30分钟停办乘机手续？

回答:
在办完乘机手续后到飞机滑行到跑道头的45分钟内，民航工作人员要进行三个方面的工作：

　　一、值机人员要结算旅客人数，行李数件、重量、货物件数、重量、邮件等，并根据以上数据进行载重平衡的结算（载重平衡结算要画平衡图，计算重心位置），然后做好舱单，送上飞机交机组，飞机方可放行，这些工作大约需要15分钟左右。

　　二、在进行上述工作的同时，广播室通知旅客开始登机，服务员要核对登机牌，清点人数。旅客上了飞机后，乘务员要再次清点人数，防止有人漏乘，然后进行飞机起飞前的准备工作，给旅客讲解有xx意事项和机上设备使用方法，检查行李架上的行李是否放好，旅客的安全带是否系好等工作。搬运队还要往机舱内装行李、货物、邮件，以上工作虽是同步进行，但全布完成需要20分钟。

　　三、剩下10分钟是飞机关好舱门滑行到跑道起始点所需的时间。所以飞机离开地面45分钟应停办乘机手续，否则航班就会延误。
